FLOW AND DEPOSITION CHARACTERISTICS OF NANOPARTICLES IN A 90° SQUARE BEND

ABSTRACT
Large eddy simulation and discrete particle model have been used to study the nanoparticles through a 90° square bend flow considering the effects of Brownian motion and turbulence diffusion. The penetration rate and the residence time of particles are evaluated under different flow conditions and various particle sizes. Results show that particles penetration rate increases with an increase in Dean and Schmidt numbers. The particle size and flow Dean number have significantly effects on the particles residence time in the bend.
